BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 233,303, dated October 12, 1880. Application filed March 29, 1880. (ModeL) To all whom it may concern Be it known that I, ANDREW WALKER, of Oincinnati,in the coun ty of Hamilton and State of Ohio, have invented a new and useful Improvement in Bottle-Stoppers, of which the following is a specification.

The invention consists in combining with the stopper caps connected by an intermediate spring, as hereinafter described.

In the accompanying drawings, Figure 1 is a view of the neck of a bottle with my improvements applied thereto, showing the stopperin place to close the bottle. Fig. 2 is a similar view, showing the stopper thrown back and the bottle open. Fig. 3 is a detail sectional view of the stopper, spring, and caps.

Similar letters of reference indicate corresponding parts.

A represents the neck of a bottle. B is a metal band surrounding the neck, under the shoulder or ring a, and secured in place by a wire, 0, passed through perforated lugs 12 on the ends of the band. From the upper edges of thebandB project two ears, D, to which are pivoted the lower ends of two links, E, the upper ends of which are pivoted to the short arms of the two branches of a bifurcated lever, G. The two branches of this lever extend on either side of a metal cap, H, and have their fulcra on two trunnions, h h, extending from said cap "diametrically opposite each other. The long arms of the two branches are merged into one arm and provided with a thumb-piece, g, occupying a position in a vertical plane midway between the two fulcra.

Each link E is bent in the form of an obtuseangled elbow, and when the stopper is in place to close the bottle the points of junction of the upper ends of the link and the short arms of 0 the levers are on one side of a vertical plane passed through the trunnions h and the pivots which connect the lower ends of the links E with the ears D, and the trunnions h rest in the elbowsof the links. (See Fig. 1.)

The stopper J is preferably of cork, but may be of any suitable material. Its upper end is inclosed by a metal cap, K. This cap and the stopper are secured together, and both are connected to the outer cap, H, by means of a spring, L, the lower end soldered to the cap K, which is secured by a gimlet-pointed screw, 1, and the upper end secured to a plain screw, m. The screw 1 is passed through a hole in the cap K and screwed into the stopper J. The screw m engages with a tap-hole in the top of the cap H. By this means the stopper J and cap H may be readily connected with the spring L and cap K or disconnected, and an old stopper removed and replaced by a new one.

When the bottle is closed, as in Fig. l, the stopper is held closely against its seat by the pressure of the spring L, and the position of the upper pivots beyond a vertical plane, above described, causes the parts to be held securely in place. When the bottle is to be opened, the thumb-piece g is pulled or pushed outward away from the neck of the bottle until the upper pivots pass to the opposite side of a vertical plane, whereupon the spring L forces the parts upward and backward to the position shown in Fig. 2.

Having thus described my invention, I claim as new and desire to secure by Letters Patout-- In a bottle-stopper, the combination, with the stopper J, of the caps H K, connected by an intermediate spring, L, as shown and (lescribed.
